H2S occurs abundantly in the world’s fossil fuel reserves and also forms as a by-product in various industrial and biological processes. In order to produce clean-burning fuels, prevent acid rain, protect pipelines and equipment from corrosion, and — most importantly — protect workers from imminent disasters, H2S levels are highly regulated using scrubbers, scavengers, sulfur recovery units, and other removal technologies.

To properly control the level of H2S in fuel, wastewater, or emissions, you need a reliable method of measuring the H2S concentration. Since safety is a major concern, only highly proven solutions are considered. For many years, that meant that customers were stuck with archaic paper tape technology, a maintenance headache with toxic consumables and frequent moving-part hardware failures.

Since its launch in 1994, OMA technology has rapidly replaced the old methods by providing the customer with solid state reliability and superior performance in an affordable package.

Explosion-Proof Models

The OMA-300 is offered in two explosion-proof formats:

Eexp

Eexp systems are purged and pressurized using a certified air-purging device. This method ensures that toxic/explosive gas is not allowed to accumulate inside the enclosure, and is ideal when instrument air is available.

Eexd

Eexd systems are contained within certified explosion-proof cast-aluminum enclosures. This method is more practical if the installation is remote or utilities are unreliable.

Sampling: H2S Analyzer

The OMA is built for direct analysis of the hot/wet sample, thus simplifying the scope of the sample system and retaining high sample integrity. From our vast experience in sampling design, we know that applications can be similar but are rarely identical. For this reason, we design and build sample conditioning systems on a project basis, working from the process to the drawing board.

Specifications: H2S Analyzer

Note: All performance specifications are subject to the assumption that the sample conditioning system and unit installation are approved by Applied Analytics. For any other arrangement, please inquire directly with Sales.
